lMPROVEMENTlN PLOWS.

Specification forming part of Letters Patent No. 209,067, dated October15, 1878; application filed August 29, 1878.

To all whom it may concern.-

Be it known that I, CHRISTIAN MYERS, of Napa City, in the county of Napaand State of California, have invented certain new and usefulImprovements in Plows and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawin g. making a part of this specification, andinwhich Figure 1 is a side elevation of a plow embodying the improvementsof my invention. Fig. 2 is a front elevation. Fig. 3 is a perspectiveview of one of the plows with the removable point detached. Fig. 4. isan elevation of the land-side of the plow, and Fig. 4 is a bottom viewof the removable point. Figs. 5 and 5 are views of the frog having thesliding portion of the land-side removed, and Fig. 6 shows amodification of the removable share and sliding land-side. Fig. 7 is adetail view.

This invention has relation to plows; and consists in the improvementsin the construction of the same hereinafter fully described, andparticularly pointed out in the claims.

In the accompanying drawing similar letters of reference indicatecorresponding parts in the several figures.

. The arms A A, carrying the spindles ,B B and the studs (3 O at theirlower ends, are journaled to the axle D at its ends. The plowbeams E arefixed upon the axle D by the hooked bolts F, and extend forward of theaxle, where they are connected by the rod G, which is also used tosecure the racks H H to the forward ends of the plow-beams, said rackshaving each a lower right-angled portion, h, through which said rod Gpasses, as shown.

A brace, I, is secured between the beams to strengthen them, and to thisbrace I the seat J is secured.

Levers K K, curved at their front ends, are secured to the sidesof theracks H H, and are provided with detents L L, which engage with theteeth of the racks H H. Arms M, having perforations N, form theconnections between the curved ends of the levers K K and the studs (J Oon the arms A A. v

The levers K K act independently of each other, and by this constructionthe plows-can be much more easily handled than Where the rock-shaftoperating the entire gang at once is employed. The drivers seat can bekept horizontal even when one of the wheels is running in a furrow andthe other upon the surface, or when the plow is being used upon thehill-side, and this, too, without an extra adjustment, as is the casewhere the entire gang of plows are elevated at one time.

The levers K K, near their fulcrums, are

sprung in against the racks to cause the detents L L to always engagewith the teeth of the racks and to change the detents from one notch toanother it is only necessary to push outwardly upon the levers and thenmove them forward or backward, as may be necessary.

Each of the plows O has its slip-share or removable point I? providedwith a tongue, Q, on its under face, which slides into a correspondin ggroove, B, one side of which is formed. by the frog S and the other bythe fixed portion T of the mold-board, secured to the frog S in theusual manner, thus forming a dovetail-joint.

The land-side wing of the slip-share 1? is provided with a lug, U, onthe inside and at the rear of said wing. slot, V, in the landside W ofthe frog S when the share I is slipped to place, and the detachableland-side W, provided with a bolt, Y, which also slides in the slot V inthe landside 7 of the frog S when the nut X, which retains it in place,is loosened, is slipped forward against the fixed portion Z of the mainland-side W and holds the lug U in the slot V, thereby firmly securingthe point I? when the nut X has been properly tightened.

To prevent the sliding portion W of the main land-side from movingunnecessarily far to the rear, a stud, a, is provided, which is securedto the inner face of the part W and enters the slot V.

A modification of the slip-share P is shown in Fig. 6, where the lug band the rear end of the land-side wing of the share P are beveled, asshown, and the forward end of the sliding portion W of the mainland-side-VV is also beveled to lap over the bevel on the lug andslip-share.

To remove or attach this slip-share P, only one nut X needs to beloosened, and that need never be entirely removed. The utility of thispart of the invention is obvious, and its sim- This lug U enters a vplicity, durability, and cheapness cannot be questioned.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent of the United States, is

1. In a plow, the combination, with the axle D, provided with the arms AA, having spindles B B and studs 0 O, and the plow-beams E E, of the rodG, for connecting said beams at their forward ends, racks H H, havingthe lower right-angled portions h h secured to said rod Gr, curvedspring-levers K K, having detents L L, and the perforated arms M N, theseveral parts constructed and relatively arranged to operatesubstantially in the manner herein shown and described.

CHRISTIAN MYERS.
